SPECIAL NOTICE: NOTICE OF INTENT TO SOLE SOURCE General Information Document Type: Special Notice Notice Sub-Type: Intent to Sole Source / Only One Responsible Source Requisition Number: 1174144 Product Service Code (PSC): 6636 (Environmental Chambers and Related Equipment) NAICS Code: 334516 (Analytical Laboratory Instrument Manufacturing) Place of Performance: USDA ARS Eastern Regional Research Center, 600 E Mermaid Ln, Wyndmoor, PA 19038 Statutory Authority The U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), Northeast Area (NEA), intends to negotiate a sole-source, firm-fixed-price contract with Opsytec Dr. Gröbel GmbH (UEI: HQ2KD3G82EP2), located at Am Hardtwald 6-8, D-76275 Ettlingen, Germany. This acquisition is conducted under the authority of FAR 13.106-1(b)(1) and AGAR 413.106 , which permits soliciting from a single source for purchases not exceeding the Simplified Acquisition Threshold (SAT) when the Contracting Officer determines that only one source is reasonably available to satisfy agency requirements. Description of Requirement & Salient Characteristics The USDA-ARS Characterization and Interventions for Foodborne Pathogens Research Unit requires the procurement of a laboratory-grade UV-LED Irradiation Chamber (Model: BSL-01i ECO+) , complete with an integrated UV-MAT touch irradiation controller, an RMD sensor calibrated to 405 nm, specialized PC operating software, and an internal sample heating/cooling plate. This system will be utilized to conduct non-thermal biological research evaluating the precise inactivation effects of blue light (specifically at a 405 nm wavelength) on foodborne pathogens across various agricultural commodities. The government has verified that the following baseline technical specifications are mandatory to support active research configurations: Wavelength Operations: Must operate at a true 405 nm blue light spectrum. Irradiance Range: Dynamically variable and adjustable from 0 to 800 mW/cm² with intensity scaling increments from 1% to 100%. Thermal Tracking: Integrated heating/cooling mechanism operating within non-thermal limits from 10°C to 40°C to preserve sample biological integrity during testing. Data Log Metrics: Built-in sensor loop measuring irradiance constantly with digital data recording rates scalable from 1 second to 1 hour. Physical Footprint: Benchtop laboratory configuration conforming strictly to the available facility spatial limitations of 40 x 30 x 50 cm. Operator Safety: Interlocked enclosure operational layout to ensure strict radiation shielding for laboratory personnel. Market Research & Justification Summary In accordance with FAR Part 10 and USDA Desk Book guidance, market research was conducted from January through March 2026. A comprehensive review of peer-reviewed scientific literature and direct inquiries across established commercial channels (including Fisher Scientific, GSA Advantage!, and alternative equipment developers…
